This application claims the benefit of U.S. Provisional PatentApplication No. 61/560,738 filed on 16 Nov. 2011, which is herebyincorporated herein by reference.

BACKGROUND OF THE INVENTION

The present invention is generally directed at solar panel supportstructures. More specifically, the present invention includes a solarpanel support apparatus securable to the ground or an affixed structurehaving a pivotal rack supporting at least one solar panel wherein therack is selectively positionable to align the solar panel at a properangle with the sun.

Over the past several decades, solar panels have become more and more ofan acceptable means by which to produce electricity or heat waterthrough use of the sun's rays. In recent years, better technology hasallowed the use of solar panels to become even more widely accepted,especially in connection with small commercial businesses andresidential use. Solar panels can assist in offsetting ever increasingenergy consumption leading to lower energy costs, and a reduced carbonfootprint.

In installing solar panels, there exist in the art both fixed mountingstructures and tracking mounting structures. The latter are much moreelaborate in design, requiring moving parts as well as a locomotivemeans and central processing unit to control its movement. For the vastmajority of small businesses, and especially for home use, trackingmounting structures remain cost prohibitive.

Fixed mounting structures generally fall within two categories: groundmounted structures and building mounted structures. With regard tobuilding mounted structures, the vase majority are roof mounted, butmounting structures on other parts of the building are known. When usingfixed position structures, either ground or building mounted, solarpanels must be installed at the proper angle to ensure the mosteffective capture of the sun's rays. Generally speaking, solar panelsmust be tilted from horizontal at an angle equal to the latitude wherethe solar panels are being installed. Further, this angle may changewith the seasons, depending on the latitude of installation. As thisangle is dependent upon the latitude at installation, a fixed mountingstructure designed for, by way of example, the northern part of theUnited States may not be appropriate for the southern part thereof.

Currently, there are no solar panel support structures available whichcan be interchangeably mounted to the ground, a building or any otherfixed structure. There are also no solar panel support structures thatcan be used universally, regardless the season of the year or latitudeat which they are placed. There therefore exists a need in the art toprovide a solar panel support structure that can be affixed to both theground, buildings or any other affixed structure. There also exists aneed in the art to provide a solar panel support structure which can beeasily modified to position the solar panel at the proper angle at anylatitude and at differing times of the year.

BRIEF SUMMARY OF INVENTION

A solar panel support apparatus in accordance with the present inventionincludes a rack assembly for supporting at least one solar panelpivotally attached to a base frame assembly. The base frame assemblyincludes two pairs of pivotally attached forward and rearwardindependently adjustable legs. A top portion of the rack assemblypivotally attaches to a top portion of each leg while a bottom portionof the rack assembly pivotally attaches to a rack support assembly. Therack support assembly includes two sets of pivotally connected forwardand rearward arms which permit pivotal movement of the rack assemblyrelative to the forward leg. The forward arm of each rack supportassembly set pivotally connects to a lower portion of the rack assemblywhile the rearward arm of each set pivotally connects to the respectiveforward leg. The rack support assembly further includes a lockingmechanism to prevent movement of the forward arm relative to therearward arm, and thus lock the rack assembly at a selected positionrelative to the forward leg. The locking mechanism includes opposingspaced-apart plates extending from the rearward arm for receiving theforward arm therebetween, or vice versa. A first pivoting pin disposedthrough a first set of corresponding apertures contained in the opposingspaced-apart plates and a first aperture contained in the forward armpivotally connect the forward arm and the rearward arm.

DESCRIPTION OF THE INVENTION

A solar panel support apparatus in accordance with the present inventionis generally indicated at 10 in FIG. 1. The apparatus 10 generallycomprises a base frame assembly 12 supporting a pivotally attached rackframe 14 for supporting one or more solar panels or arrays 16. As bestillustrated in FIGS. 2 through 4, the base frame assembly 12 includes apair of spaced-apart rearward legs 18, each respectively pivotallyattached to a pair of spaced-apart front legs 20 by means of a bracket22 and accompanying pin or bolt 24. The rear legs 18 are supported by abrace 26 including a first segment 28 and a second segment 30 pivotallyattached at central portions thereof and secured to the rear legs 18 bypins or bolts 32. Anchoring foot pads 34 and pins or bolts 36 areprovided to pivotally secure each leg 18, 20 to the ground or any othersuitable affixed structure, including a rooftop, post, footing or sideof a building. To accommodate nearly every conceivable terrain oraffixed structure, both the forward legs 20 and the rearward legs 18 aretelescoping to independently increase or decrease their overall length.This is accomplished by means of a first top portion 38 for rear leg and39 for forward leg slidably disposed within a second bottom portion 40for rear leg and 41 for forward leg. Preferably, the top portion 38, 39are provided with a variety of pre-drilled apertures 42 at varyinglocations for receiving a pin 44 therethrough to be mated with acorresponding aperture in the respective bottom portion 40, 41. Itshould be noted, however, that providing a plurality of apertures 42 inthe bottom portion 40 to be mated with an aperture of the top portion 38is well within the scope of the present invention. It should be furthernoted that it is well within the scope of the present invention that theend-user drill apertures to customize the positioning of the first topportion 38 relative to the second bottom portion 40 to adjust the heightof each leg 18, 20. In this manner each forward leg 20 and rearward leg18 can be independently adjusted to account for varying terrain orheights of a structure to which the base frame assembly 12 is securable.

The rack frame assembly 14 preferably includes a rectangular formationhaving opposing top and bottom members, 46 and 48, respectively attachedto opposing side members 50 with use of brackets. The rack frame 14 isdesigned to be field adjusted by the end user to accommodate solarpanels or arrays 16 of varying dimensions and from various manufactures.Optional horizontal and vertical cross members, 52 and 54, respectively,may be provided to secure solar panels or arrays 16 to the rack framemembers 46, 48, 50. Brackets 56 permit pivotal attachment of a topportion of the rack frame assembly 14 to the forward legs 20, and inparticular the top portions 38 of the forward legs 20. Opposing sides ofa bottom portion of the rack frame assembly 14 each connect torespective forward legs 20 by means of a rack support assembly 58.

The rack support assembly 58 includes a forward arm 60 pivotallyconnected to the racking frame assembly 14 by means of a bracket 62, anda rearward arm 64 pivotally connected to the respective forward leg 20by means of a bracket 66. Preferably, proximal end of forward arm 60pivotally connects to the lower portion of the rack frame assembly 14,and proximal end of rearward arm 64 pivotally connects to the lowerportion 40 of the forward leg 20. It should be noted though that it iswell within the scope of the present invention to attach the forward arm60 at differing locations along respective side members 50 of theracking frame assembly 14, as well as attach the rearward arm 64 atdiffering locations on the forward leg 20. The forward arm 60 and therearward arm 64 pivotally connect to one another at distal ends wherethey can be locked to one another by means of a locking mechanism 68.The locking mechanism 68 includes opposing ears or plates 70 extendingfrom the rearward arm 64 and spaced-apart from one another so as toreceive the forward arm 60 therebetween. Alternatively, as one skilledin the art will recognize, it is well within the present invention toprovide the ears 70 attached to the forward arm 60, with the rearwardarm 64 disposing therebetween. Each ear 70 contains correspondingapertures 72 for receiving a pin 74 disposable through a cooperatingaperture 76 positioned through the forward arm 60 to pivotally attachthe forward arm 60 to the locking mechanism 68. When installed, the racksupport assembly 58 preferably permits the rack frame assembly 14 to bepositionable relative to the forward leg 20 between zero degrees, orparallel to the forward leg 20, and 90 degrees, or perpendicular to theforward leg 20, and an infinite number of positions therebetween. Itshould be noted, though, that it is well within the scope of the presentinvention to either modify the length of the forward and rearward arms,60 and 64, respectively, or the positioning of the attachment of theforward and rearward arms, 60 and 64, respectively, to respectiveracking frame assembly 14 and forward leg 20 to modify the positioningangle of the racking frame assembly 14 relative to the forward leg 20 togo beyond 90 degrees.

To lock the rack frame assembly 14 at a selected position, two methodsare described. The first method accommodates an infinite number ofpositions of the rack frame assembly 14 within the arc range thereof. Asis known in the art, the preferred angle of the solar panel or array 16,and thus the rack assembly 14, is first determined. Upon determining theselected position of the rack frame assembly 14, the user drills asecond set of corresponding apertures 78 through each ear 70 of thelocking mechanism 68 and a second aperture 80 through the forward arm 60at the selected position of the rack frame assembly 14. A second pin 82disposable through the second set of apertures 78 and the secondaperture 80 prevents pivotal movement of the forward arm 60 about therearward arm 64, and the two are locked in place. If later anotherpositioning of the rack frame assembly 14 is desired, the user simplydrills another set of cooperating apertures in the same manner asdescribed to accommodate the updated selected position, as illustratedin FIG. 5. Alternatively, a second method includes providing one or moreadditional sets of cooperating apertures 78 through the ears 70 and forreceiving the second pin 82 to lock the rack frame assembly 14 at apre-selected position. The second method could accommodate a widevariety of preselected positions within the arc range of the rack frameassembly 14, and may allow for more than one positioning depending onspecific needs of the user. Using either the first method or the secondmethod, once the second locking pin 82 is properly positioned, movementof the forward arm 60 relative to the rearward arm 64 is not permitted,and the racking frame assembly 14 is locked into place at the selectedposition.

Alternatively, it is well within the scope of the present invention toremove the rear legs 18 and attach only the forward leg 20 a fixedstructure, for example a vertical wall of a building. The racking frame14 and rack support assembly 58 remain and operate as previouslydescribed.

It is recognized there are multiple variations beyond what are outlinedin the detailed description to accomplish the objectives set forth bythe current invention. Further alternative embodiments provideadditional utility of the device for the convenience of the user. Assuch, although the present invention has been described with referenceto preferred and alternative embodiments, workers skilled in the artwill recognize that changes may be made in form and detail withoutdeparting from the spirit and scope of the invention.
